This notification is in accordance with NCDEQ Requirements for Municipal Solid Waste Landfill Facilities Section .1634(d), which states the following: “After obtaining the results from the initial or subsequent sampling events required in Paragraph (b) of this Rule, the owner or operator shall: (1) Within 14 days, submit a report to the Division and place a notice in the operating record identifying the Appendix II constituents that have been detected;” Groundwater sampling was completed by Environmental Sampling & Services, Inc. (ES&S) on January 30, 2018. Analytical testing was performed by Pace Analytical Services, LLC for the initial Appendix II sampling event for each of the site’s ten groundwater monitoring wells: MW-1R, MW-2R, MW-3R2, MW-4, MW-5, MW- 6, MW-7, MW-8, MW-9, and MW-10. Results were received by Jett Environmental Consulting on February 27, 2018. The attached Table 1 summarizes the Appendix II constituents that were detected above the solid waste section limits (SWSLs) during the First Semi-Annual 2018 event. The parameters detected (barium, benzene, and cobalt) are consistent with past events. The inorganic and organic constituents on Table 1 are also on the Appendix I Detection Monitoring list. The attached Table 2 summarizes the Appendix II constituents that were reported at estimated values between the method detection limit (MDL) and the SWSL. The constituents on Table 2 are also on the Appendix I Detection Monitoring list, with the exception of an estimated value of total mercury at MW-5 (J 0.1 ug/L). Any analyte detected at a concentration greater than the MDL but less than the SWSL is believed to be present, but the uncertainty in the value is high (i.e. laboratory interferences). As a result, the actual concentration is estimated. No further action is required based on the estimated results. The full groundwater report and statistical evaluation is currently being compiled and will be submitted per Sections .1632 and .1633. The groundwater report will provide recommendations regarding Assessment and Appendix II monitoring activities. Should you have any questions or concerns, please contact Mr. Derek Bouchard at (314) 302-3634 or Steve Jett at (314) 496-4654. 2 Sincerely, Steve Jett, LG #1825 Owner, Jett Environmental Consulting, PLLC (C-517) Attachments: Table 1 - Appendix II Detections Above the SWSL Table 2 – Appendix II Estimated Results Below the SWSL cc: Derek Bouchard, Republic Services, Inc.
